      A:

      Simple it is for a length of oxygen barrier pex most often buried in a floor.. This one I believe allows you to equalize the flow without extra tools of multiple loops of radiant heat. I use them in garage floors most of the time and they work fine.

      A:

      A loop (also known as a run or circuit) is a length of tubing that runs to and from a manifold. In in-floor systems, it's usually necessary to break piping runs into separate loops to keep head pressure at a reasonable level and make sure the water does not got cold during the run.

    Why do i need these manifolds. Cant i simply build my own on site. What do you mean when you talk about balancing and flow meters

      A:

      You can use valveless manifolds if your loops are all close the same length and part of the same zone, but this manifold gives you the ability to adjust flow between loops.

      A:

      You can build your own from standard copper pipe and fittings if you like.
      The pre-built ones save time, and are more compact. You can use a
      regular ball valve for each outlet on your custom manifold, and you
      will need the appropriate fittings to attach the PEX tubing to each loop.
      The flow meters show the rate of water flow though each loop in the
      manifold, in Gallons per Minute. They aren't really needed, but are nice
      to have. As you adjust the balancing valves on each loop, you can see
      the flow rate change on the meters.
      The balancing valves are to adjust the flow of water through each loop
      individually. Depending on the installation, it may be desirable to have
      more water flow through some loops than others. In mine, we lower the
      flow for loops that heat bedrooms, so the bedrooms always stay a little
      cooler than other rooms in the same zone. Or, if some loops are much
      shorter than others, you can reduce the flow to them, while leaving the
      full flow to the longer loops. That will help even out the heat distribution.
      All part of balancing the system to your installation and personal tastes.

      A:

      Almost all systems with multiple zones and a manifold can benefit from balancing. Since a single pump is pushing the heated water through multiple zones, it is helpful to have some way of adjusting to provide more hot water to longer zones or zones that heat larger spaces than to smaller zones. That way, if multiple zones are simultaneously calling for heat, one of them won't get the lion's share of the heat and heat up real quickly, while the others take forever to get warm.
      Balancing valves on each branch of a manifold, along with flow meters to visually see how much hot water is flowing to each zone, are the easiest solution to this problem. You could probably make up the manifold with balancing valves and flow meters yourself, but it would probably cost more than a pre-made unit.

  • 6 Loop Radiant Heat Manifold Package (1/2" PEX)

    Q:

    I have a 6 loop brass pex manifold and this morning I awoke to find one of the loops is barely running any water thru it as the flow meter barely reads any flow rate....adjusting it does not change the flow meter yet is seems to be flowing a very minor amount...the other 5 loops work fine, flow meter changes when changing the adjustment yet this one loop doesn't seem to be working properly...the outgoing manifold with the meters on it is mounted upside down so the meters are pointing to the floor...the return manifold is also mounted upside down as all tubing enters both manifolds from the top side....is it possible there is some kind of blockage in this one loop right at the manifold?
    Thanks for your help

      A:

      It is possible that there is some sort of a blockage, as flow meters that are mounted upside down can accumulate sediment. The flow meters can be replaced (part MP172S).

      A:

      You can install the manifold upside down, but the flow meter itself will not function properly if it's upside down.

      A:

      Your goal should be to get the flow meters to have equal readings. The settings needed to do this depend on the flow through each loop.

  • 4 Loop Radiant Heat Manifold Package (1/2" PEX)

    Q:

    I had a heating contractor install one of these 4 loop manifolds a few years ago... today when I turned on the system, I had water leaking from the top of one of the control valves. Turning off the system, I see that the brass male thread has completely separated from the manifold (that is, threads are in the nut as threaded shaft has broken from the manifold body). Seems like the brass is very thin at this thread. What is the warranty on replacement in this case? System has been untouched since installation?

      A:

      The inlets on this unit are EK32 which is a size that is specific to the manifold. In order to adapt to your supply lines, you need supply adapters. These can be found here: http://www.pexsupply.com/Mr-PEX-Manifolds-Adapters-1199000
